Brazil's national airport authority Infraero will invest 748mn reais (US$456mn) in capital Brasília's Juscelino Kubitschek international airport up to 2014.

The expansion and improvement works at the airport are aimed not just at preparing the city for the 2014 World Cup, but also at meeting long-term passenger demands, Infraero's director of engineering studies and projects, Jonas Lopes, said during an event held in the capital.

The first phase of work includes expanding the main airport area from 80,000m2 to 175,000m2, allowing the facility to handle 32.6mn passengers each year. The work has already been tendered and this phase should be complete by 2014, according to an Infraero release.

The federal district government is also planning a project to widen the DF-047 road, which connects the airport with the city center.
